The average force changes the velocity of golf ball to increase from #0 ms^-1# to #102 m^-1s# in time #t=0.59 ms#.

From Newton’s Second Law we know that
Average Force #=# mass #xx# acceleration

Also that
Acceleration #= ("change of velocity" (Deltav))/(Deltat)#
#:.# Average Force #= "mass" xx ("change of velocity" (Deltav))/(Deltat)#

Inserting given values we get

Average Force #= 0.050 xx 102 / (0.59xx10^-3) = 8644.1 N# , rounded to one decimal place
